Question

which is the site of the most atp production during cellular respiration?
○ nucleus
○ mitochondrion
○ cytoplasm
○ chloroplast

Explanation:

• The nucleus is the control center of the cell, not involved in ATP production during cellular respiration.
• The mitochondrion is the site of the Krebs cycle and the electron transport chain, which produce the majority of ATP (about 30 - 32 ATP per glucose molecule) during cellular respiration.
• The cytoplasm is where glycolysis occurs, producing a small amount of ATP (2 ATP per glucose molecule).
• Chloroplasts are involved in photosynthesis, not cellular respiration.

Answer:

B. mitochondrion
